Cov txheej txheem electroplating yog: degreasing-cleaning-tsis muaj zog acid activation-tu-tooj liab plating hauv qab-ua kom-tsim-plating dub npib tsib xee-ntxuav-passivation-tu-drying-over-the-frame, cov xim dub nickel plated los ntawm cov xim dub nickel plating. Cov txheej txheem nickel feem ntau muaj 40 feem pua -60 feem pua nickel, 20 feem pua -30 feem pua zinc, 10 feem pua -15 feem pua sulfur, thiab li ntawm 10 feem pua cov organic teeb meem.
Thaum lub sij hawm electroplating txheej txheem, cov sulfur nyob rau hauv thiocyanate ions yog hloov dua siab tshiab rau hauv sulfide ions, thiab ua dub nickel sulfide nrog npib tsib xee. Cov tooj liab hauv qab yog ntxiv rau hauv cov txheej txheem. Lub luag haujlwm tseem ceeb yog ua kom npib tsib xee plating yooj yim dua hauv cov txheej txheem tom qab thiab txhim kho corrosion kuj ntawm cov ntsia hlau. Feem ntau, lub thickness ntawm tooj liab hauv qab yog li 1 micron. Yog hais tias lub thickness ntawm cov tooj liab hauv qab yog nce, qhov corrosion kuj tuaj yeem txhim kho, tab sis cov khoom xyaw yuav nce ntxiv.
Tom qab kev sim ua kom zoo ntawm cov ntsia hlau siv los ntawm ntau lub tuam txhab electroplating, kev lag luam-theem tsis kam rau cov tshuaj ntsev nruab nrab feem ntau yog 6-12 teev. Yog tias qhov sib piv qhov tseeb ntawm ntau cov khoom siv ntxiv siv hauv electroplating thiab cov khoom siv raw zoo tuaj yeem txhim kho, cov khoom siv raw zoo tuaj yeem txhim kho.
Nyob rau hauv cov txheej txheem npib tsib xee plating, cov tuam txhab hluav taws xob dav dav yuav hla cov roj lossis foob txhawm rau txhawm rau txhim kho corrosion, thiab cov ntsia hlau siv tsis tuaj yeem siv cov roj los txhim kho cov ntsev tsuag lub sij hawm txiav txim siab qhov cuam tshuam corrosion ntawm cov khoom yas. Lub sij hawm ntawm qhov nruab nrab ntsev tshuaj tsuag yog 8 teev. Nws tsis ruaj khov nyob rau hauv niaj hnub thwmsim, thiab muaj ob peb batches ntawm niaj hnub nruab nrab ntsev tsuag tsis ua hauj lwm.
Nws yog ib qho yooj yim kom paub qhov txawv ntawm cov tsos vim hais tias dub nickel yog tsaus dua li lwm cov zinc dub, oxide dub thiab electrophoretic dub.
